What does it mean to size a bet?
Sizing is the decision that comes after “should we bet?”, how much? It's the quiet skill that decides survival: the same picks with bad sizing go broke, and with good sizing they compound. In your fund, size follows edge and conviction, inside your caps Never excitement.
Why sizing beats picking
Two funds can make identical picks and end in opposite places. The one that bets a huge share of its wallet on its favorites eventually meets the losing streak that ends it; the one that sizes steadily is still there when the positive EV finally shows up in the totals. Markets forgive wrong opinions held small. They don't forgive right opinions held too big.
How your CEO sizes
- Edge sets the appetite A wide, well-evidenced gap earns more than a thin one.
- Conviction scales it Fragile reads get survival-sized positions.
- Your caps bound it The per-bet ceiling and total exposure limit are walls, not suggestions. No thesis, however beautiful, crosses them.
The feeling it removes
The classic human failure is betting biggest when most excited, precisely when judgment is worst. Rule-driven sizing deletes that correlation: the fund's stake reflects the evidence, not the adrenaline. It's the least glamorous part of the craft, and the one that keeps everything else alive.
